CARRIER.

Application filed November 20,

Be it known that we, GEORGE BEATTY, WILLIAM G. BEATTY, and MILTON J. BEATTY, of Fergus, in the county of Wellington and Province of Ontario, Canada, have invented certain new and useful Improvements in Carriers; and we hereby declare that the folof the same.

This invention relates to a carrier having a carrier-frame comprising two sides separated by spacing-bars interposed between them below-the path of the track and rigidly held in their assembled condition by fasteningbolts and nuts, four track-wheels mounted on axles arranged in two oppositely disposed sets and projecting inwardly from theinner faces of the carrier-frame-sides above the path of the track with an unoccupied space between the track-wheels and axles on one side of the carrier and those on the other side to permit the carrier to freely pass any obstruction on the track, a lever pivoted atone end to one side of the carrier-frame to hold the fixed end of the draw-rope, a rope-guide at the opposite side of the carrier-frame extending below the bottom thereof, a ropegrip pivoted to the last mentioned side of the carrier-frame above and in line with the ropeguide, two guide-pulleys above the ropegrip, journaled on axles connected to the carrier-frameside with the rope-course between them in line with the rope-course through the rope-grip and rope-guide, a rope-grip-releas to position the rope-grip to allow the drawrope to run freely through the rope-course and to which is pivoted the other end of said lever, a support for the rope-grip-release to maintain it temporarily in an operative position, a carrier-lock forming part of the ropegrip-release and positioned by the latter when actuated to engage two stop members connected to the track so that it will arrest the carrier at the loading point during the hoisting of the load and a cam on the track to engage the rope-grip-release and move it into an operative position when the carrier reaches the loading point, as hereinafter described and particularly pointed out in the appended claims.

For a full understanding of the invention reference is to be had to the following description and. to the accompanying drawings, in which,

Specification of Letters Patent.

Fig. 2 is a similar view to Fig. 1, with the rope-grip positioned to grasp the draw-rope and prevent it descending through the ropecourse. Fig. 3 is a perspective view of the carrier looking at it from, the opposite side to that shown in Fig. 2. Fig. 4 is a longitudinal section of the carrier showing the parts in the same position as in Fig. 1. Fig. 5 is a similar view to Fig. 4 with the parts in the same position as in Fig. 2. Fig. 6 is a detail view of the rope-grip release. Fig. 7 is a View of the inner face of one of the carrier-frame-sides showing part of the slideway for the ropegrip-release. Fig. 8 is a perspective view of the support for the.rope-grip-release. Figs. 9 and 10 are perspective views of the ropegrip-release and its slideways showing the parts in the positions shown in Figs. 1 and 2 respectively. Fig. 11 is a perspective view of the rope-grip. Fig. 12 is a perspective view of one of the members of the rope-grip. Figs. 13 and 14 are sectional views of the rope-grip with the parts in the same position as shown in Figs. 2 and 1 respectively, and Fig. 15 is a side elevation of the rope-grip-release and lever.

Like letters of refernece refer to like parts throughout the specification and drawings.

The carrier-frame consists of two sides a a separated by spacing bars I) located above the bottom of the sides of the carrier-frame but below the path of the track 0 and held assembled by bolts (1 d and nuts f f Projecting inwardly from the inner faces of the carrier-frame-sides above the track path are four studs g arranged in two oppositely disposed sets with the studs of each set in line, and mounted on the studs 9 are flanged track wheels h to move the carrier from one position to another on the track as hereinafter described. Pivoted to the lower end of the side a at ap roximately the middle thereof is one end 0" a lever a from which is suspended a rope-bail i, to which is adapted to be attached the fixed end of the drawrope j and attached to the side a isa ropeguide it having a rope-course Z through which the draw-r0 e passes to the rope-grip pivoted to the carner-frame side a vertically above the rope-guide lc and the rope-course there through. The rope-grip consists of two bifurcated hinge members m' m, the shanks of which are pivoted to the carrier-frame- 7 side a, by pivot bolts 0, and two clasps 1),

having trunnions q and a clasp p having trunnions g mounted in the forks m of the hinge members, the centers of the trunnions g being out trunnions q so that they will cause the clasps to separate as thehinge members oscillate upward and cause them to come together as the hinge members oscillate downward.

Mounted on the outer face of the carrier frame side a, above the rope-grip, are du plex guide pulleys r, r with the rope-course between them in line with the rope-course through the rope-grip and rope-guide, and protecting the guide-pulleys is a pulley frame tfastened to the carrier frame side a, by two sets of bolts u u fitted with nuts 12 o. For convenience of manufacture the bolts u are utilized as the axles for the guide-pulleys, in addition to assisting the bolts u to fasten the pulley frame to the carrierframe. In the inner face of the carrier-frame-side 0/, as shown in Figs. 9 and 10, is a vertical slide-way y, in which is movable the ropegrip-release z and to which is hinged the other end of the lever a.

Registering in an aperture 1) in the lower end of the rope-grip-release is a pin 0 which projects from the lower one of the hinge members m. Extending above the track from the upper end of the rope-grip-release is an arm at to be engaged by a cam e mounted on the track. Pivoted to the lower part of the carrier-frame is a support g havmg an arm 71 to engage the detent lug 11 formed on the side of the r0pegriprelease. The cam e is positioned on the track vertically above the loading point and as the carrier approaches thereto the cam engages the arm at as shown in Fig. 5, and raises the rope-griprelease into the position shown in Fig. 4, so that it will actuate the rope-grip to release its grasp on the draw-rope. The support 9 then moves by gravity to bring the arm h into position where it will engage with the detent lug i and uphold the ropegrip-release, to maintain the rope-gri inoperative while the carrier is at the oading point.

To arrest the carrier at the loading point the under face of the track is provided with two detent stops j, preferably located below the ends of the cam e and engaging these stops when the rope-grip-release is actuated is a carrier lock is forming part of and pro jecting from the inner face of the rope-griprelease. (Jo-operating with the carrier is, a pulley-block Z, consisting of a pulley frame 0, with a grooved pulley wheel 0 mounted therein and a hook q swiveled to the ulley frame. The free end of the hook is ifurcated and pivoted between the forks thereof is a spring tensioned latch 7" which. normally of line with the centers of the.

extends across the opening at the mouth of the hook and engages the shank on the opposite side to prevent the withdrawal of the ring of the fork or sling.

The draw-rope j extends from the ropebail t through the rope-course Z in the ropeguide is through the rope course between the clasps p p of the rope-grip, and between the guide-pulleys r 1", over either of which it extends parallel with the track rail to an idler (not shown). When the carrier is at the loading point the rope-grip-release z is posi tioned to engage and uphold the rope-grip so that the clasps 1) 10 will be positioned to release the draw-rope and permit it to move freely through the rope-course between them and the carrier lock 74" is then positioned to engage the detent stops j and hold the carrier at the loading point, until the draw-rope has raised the pulley-block into contact with and upset the support g for the rope-grip-release .2. The upsetting of the support 9 remove the arm 72/ from beneath the detent lug 1', so that the rope-grip-release can descend to permit the rope-grip to oscillate into a position where it will seize the draw-rope and securely hold it with its suspended load until the rope-grip-release has been actuated by the cam. The strength of the grasp of the rope-grip on the draw-rope is intensified by the weight of the load suspended from the bail which causes the lever a to draw upon the ropegrip-release and through the agency of the latter lock the parts of the rope grip against. the draw rope and prevent the latter from any ordinary cause moving through them until they have been again released. As the rope-grip-release descends the carrierlock moves out of the path of the detent stops to allow the carrier to freely move away from the loading point with its load securely suspended.

When the carrier arrives at the delivery point, the load is deposited and the carrier may then be returned to the loading point the approach to which is uninterrupted except by the lifting cam which as soon as the arm (1'' comes into contact with it raises the rope-grip-release into its operative position to disengage the grasp of the rope-grip on the draw-rope to allow it to descend for its next load. By providing the carrier-frame with two guide pulleys the direction of the drawrope may be quickly reversed to draw toward either end of the track. By means of this construction and arrangement of parts the gripping device will grasp the perpendicular part ofthe draw-rope before it passes over the guide pulleys so that the weight of the load may be utilized to securely lock the rope-grip against the draw-rope.
